Using a lawn mower for regular maintenance of the grass in your lawn is essential to remove weeds and unwanted growth and keep the grass healthy and green.
While using a lawn mower, a lot of debris, dust and leaves often fly around. These particles would enter into your lawn mower and either clog it or slowly damage it if it wasn’t for the air filter of your lawn mower.
Air filters are a highly crucial component of your lawn mower that requires regular and diligent maintenance. Without a properly functioning air filter, the engine of your lawn mower will stop working much sooner than its expected longevity.
Maintaining and replacing an air filter is simple and affordable and can save you hundreds of dollars rather than having to replace your lawn mower entirely in case of damage.
Depending on the model, your air filter might be one of three types. Some lawn mowers have a filter made only of foam and some lawn mowers have a paper air filter. The third type of lawn mower has a combined air filter made of one layer of foam and one layer of paper.
It is essential to clean the foam filter frequently and replace it regularly since it goes through wear and tear over time.
Cleaning the paper air filter can be more tricky as it is much more sensitive and can get damaged during the process. Paper air filters are quite affordable and can be replaced easily if the need arises.
However, with a little bit of caution, you can clean your paper air filter and extend its use for as long as it allows.
We’ve put together this quick and simple step-by-step guide that will tell you all you need to know about how to clean your lawn mower paper air filter.
The first thing you will need to do to clean your lawn mower paper air filter is to make sure that the engine is completely turned off. Sometimes the machine might still be running after it is turned off, so make sure all the parts have stopped moving altogether.
It can be dangerous to open the air filter while the engine is running as that can cause significant damage to the lawn mower and might even make the lawn mower stop working entirely in the future.
To make sure that the engine does not turn on while you are working to clean the paper air filter, take out the lawn mower’s spark plug. This will turn off the energy for the lawn mower completely.
The next thing you need to do to clean your air filter is to remove the outer covering. You will usually find the air filter on top of the lawn mower inside a case made of plastic or metal.
If you can’t find the air filter, you can consult your lawn mower model’s manual to ascertain where the air filter is. The manual will also tell you how to remove it.
Some covers can be removed using a built-in tab on the case itself or you might need to use a screwdriver to unscrew the covering from the lawn mower. After removing the casing, you can take out the air filter.
After taking out the air filter, use one or two paper towels to plug the opening so that no dust goes inside the engine during this process.
After this, you need to take out the air filter and slowly remove the foam part of the filter. This will come off easily without any tools if you gently peel it out. If your lawn mower does not have a foam air filter, then you can skip this step.
Once you take out the foam air filter, check it to see if it is just dirty or if it also has signs of damage such as splotches or tears. If it is damaged, you can replace the foam filter.
Otherwise, if there is no damage but there are many particles stuck in the filter, you will need to clean it.
The foam filter is relatively simple to clean. All you need to do is wash it with water and soap thoroughly a few times. Make sure to wring out all the excess water and then allow the foam filter to dry completely in the air or under sunlight.
After it has dried completely, you will need to oil the foam filter as the grease is an essential part of the filtering process. You can find specific foam filter oil at a hardware store. Using this will ensure that the oiling does not damage the paper filter inside.
To oil the foam filter, all you need to do is put the oil on the filter and then massage it with your hands to spread it evenly. Then, blot out any excess oil with some paper towels.
After this, you can gently take out the paper air filter. To see if it is damaged and needs to be replaced, simply hold the paper up towards the light. If the paper has become opaque, then it will need to be replaced.
Otherwise, you can go ahead and clean the paper air filter by gently tapping it on a hard surface to allow any loose particles of dust to fall off.
You cannot use water or any solvents to clean the paper air filter and using compressed air will also damage the filter.
The only appropriate option to clean the air filter further is a vacuum cleaner with a hose. Use this to clean both sides of the paper air filter gently.
That concludes the process of cleaning your lawn mower paper air filter. Once you are done cleaning, use a dry paper towel to gently clean the opening in the engine where the air filter is supposed to be installed.
Then, go ahead and place the air filter components as they were installed before, put the air filter back into the opening and screw the cover shut.
